What is the recommended treatment for a pregnant patient with a confirmed bacterial vaginosis?

In the case of a pregnant patient diagnosed with bacterial vaginosis (BV), metronidazole is the recommended treatment. This medication is effective against the anaerobic bacteria that cause BV. Importantly, it has been shown to be safe for use during pregnancy, particularly in the second and third trimesters, making it the first-line choice.

While some other antibiotics are effective for different infections, they may not be appropriate for BV during pregnancy. For instance, amoxicillin is typically used for other bacterial infections but is not recommended specifically for BV. Acyclovir is an antiviral drug used for herpes infections, irrelevant to BV treatment. Ciprofloxacin, a fluoroquinolone antibiotic, is generally avoided in pregnancy due to potential risks to the developing fetus.

Thus, metronidazole stands out as the safest and most effective treatment option for bacterial vaginosis in pregnant individuals.
